This paper extends the method of discounted cash flows to value investment projects through incorporating real options. It is assumed the cash flows generated by the firm are correlated with macroeconomic fundamentals, particularly with the interest rate. It is also assumed that the cash flows...

This research develops, under the assumption of complete markets, a stochastic model that explains the decision making process of a rational consumer-investor selecting a portfolio in a market risk environment subject to his budget constraint. The proposed model is developed in the framework of...

This paper develops, under the framework of a small, open, and monetary economy, a stochastic model of inflation stabilization taking as a nominal anchor the exchange rate when credibility is imperfect. The agents have expectations driven by two processes: a diffusion-jump process for the...

En este articulo se presenta de manera completa, rigurosa y compacta, la teoria clasica de las finanzas (TF). No pretende introducir teoremas novedosos, sino solo entretejerlos usando un metodo que nunca ha sido utilizado en la demostracion de representaciones de utilidad: el teorema de Tarski...

Today's retirees face the daunting task of determining appropriate investment and spending strategies for their accumulated savings. Financial economists have addressed their problem using an expected utility framework. In contrast, many financial advisors rely instead on rules of thumb. We show...

Experimental work on decision-making shows that, when people evaluate risk, they often engage in narrow framing: that is, in contrast to the prediction of traditional utility functions defined over wealth or consumption, they often evaluate risks in isolation, separately from other risks they...

We study the asset pricing implications of Tversky and Kahneman's (1992) cumulative prospect theory, with particular focus on its probability weighting component. Our main result, derived from a novel equilibrium with non-unique global optima, is that, in contrast to the prediction of a standard...

We argue that narrow framing, whereby an agent who is offered a new gamble evaluates that gamble in isolation, separately from other risks she already faces, may be a more important feature of decision-making under risk than previously realized. To demonstrate this, we present evidence on...

We argue that quot;narrow framing,quot; whereby an agent who is offered a new gamble evaluates that gamble in isolation, separately from other risks she already faces, may be a more important feature of decision-making than previously realized. Our starting point is the evidence that people are...

Do asset prices affect real activity? This question has taken on a new importance in recent years, as asset values first surged at the end of 1990s and, thereafter, dramatically retreated. This report reviews the available theoretical and empirical evidence regarding asset price and wealth...
